Abstract

Soiling is a critical, site-specific challenge that affects the performance and economic viability of photovoltaic power plants. This study evaluates the effectiveness of an outdoor microscopy method under the specific climatic conditions and dust composition of the Mid-south region of Morocco. Semi-empirical models were developed to correlate the Soiling Coverage Index with losses in optical and electrical performance. Additionally, a comprehensive analysis of local dust, encompassing its chemical composition, morphology, and size distribution, was conducted. Results indicate quartz as the predominant mineral in Benguerir city’s dust particles, with diameters ranging from 0 μm to 26 μm. Additionally, following a 2-week exposure with no rainfall, a dust density of 2.5 g/m2 accumulated on the deployed glass coupons, resulting in a soiling ratio of 6.9 % and a relative transmittance loss of 15.19 %. The surface coverage index, as calculated by the outdoor microscope, was 9.16 %. Furthermore, the evaluation of this metric revealed strong positive correlations (r2 = 0.95 to 0.99) with key soiling indicators such as dust density, soiling ratio, and transmittance loss. These findings underscore the efficacy of the outdoor microscope as a fast, low-cost, and reliable soiling monitoring sensor, offering valuable insights for future monitoring and mitigation efforts.

光伏技术污垢的建模、评估和特征描述。更好地理解灰尘沉积与性能损失之间的关系
污垢是影响光伏电站性能和经济可行性的一个关键性、因地制宜的挑战。本研究评估了摩洛哥中南部地区特定气候条件和灰尘成分下户外显微镜方法的有效性。研究人员开发了半经验模型,将污垢覆盖指数与光学和电气性能损失联系起来。此外,还对当地灰尘进行了全面分析,包括其化学成分、形态和粒度分布。结果表明,石英是本盖尔市灰尘颗粒中最主要的矿物,直径从 0 微米到 26 微米不等。此外,在无降雨的情况下,经过两周的曝晒后,已部署的玻璃样品板上积累了 2.5 克/平方米的灰尘密度,导致脏污率为 6.9%,相对透光率损失为 15.19%。室外显微镜计算得出的表面覆盖指数为 9.16%。此外,对这一指标的评估显示,它与灰尘密度、脏污率和透光率损失等主要脏污指标之间存在很强的正相关性(r2 = 0.95 至 0.99)。这些发现强调了室外显微镜作为快速、低成本和可靠的脏污监测传感器的功效,为未来的监测和缓解工作提供了宝贵的见解。
